861297 ÷ 17 
The aim is to understand the frequency of 17 in 861297.

Step 1:
8 divided by 17 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 17

Step 2:
17 can be fit into 86 5 times, resulting in a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 1 after subtracting 85 from 86.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 17

Moving on to step 3:
17 goes into 11 0 times with a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
If we take 0 away from 11, we end up with 11.
Fetch the next digit (2) from the dividend, attach it to 11 and continue: 112 / 17

Advancing to step 4:
17 can be fit into 112 6 times, resulting in a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 506.0
Subtract 102 from 112 to get 10.
Take the next digit (9) from the dividend and append it to 10, then repeat: 109 / 17

Advancing to step 5:
The number 17 fits into 109 6 times, leaving a remainder of 7.
Write down 6 as next digit of the result. 
Result so far: 5066.0
Subtracting 102 from 109 leaves us with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 17

Moving on to step 6:
If we divide 77 by 17, we get 4 and a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 50664.0
Subtract 68 from 77 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
17 can be fit into 90 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 50664.5
Deduct 85 from 90 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
50 divided by 17 is 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 50664.52
If we subtract 34 from 50, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 9:
When dividing 160 by 17, we get 9 with a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 50664.529
Subtracting 153 from 160 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 10:
When dividing 70 by 17, we get 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 50664.5294
If we subtract 68 from 70, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 11:
When dividing 20 by 17, we get 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 50664.52941
If we take 17 away from 20, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 12:
If we divide 30 by 17, we get 1 and a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 50664.529411
Subtract 17 from 30 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The quotient of the division is 50664.529411, and the remainder is 1.3e-06.
